During the 1900s, the following genetic discoveries were made: • DNA is the molecule responsible for inheritance.
• There are four bases in DNA, and they combine in a specific way. Adenine pairs with thymine, and guanine pairs with
cytosine.
• DNA is a double helix. The sugar molecules form the backbone, and the bases are connected by hydrogen bonds in the
middle.
• Enzymes that can cut and copy sections of DNA are identified and isolated.
As a result of these scientific discoveries, scientists are now able to

A.
determine some organisms' genetic sequences.
B.
change portions of genetic code to treat disease.
C.
clone certain organisms.
D.
all of these

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
